The exiled leader of China's Uighur minority firmly distanced herself from Al-Qaeda, condemning the group's threats to attack Chinese interests in retaliation for the Muslims' deaths.

Rebiya Kadeer, the Washington-based head of the World Uighur Congress, said she opposed the use of violence in her campaign to bring greater rights for the ethnic group in China's northwestern Xinjiang province.

"Global terrorists should not take advantage of the Uighur people's legitimate aspirations and the current tragedy in East Turkestan to commit acts of terrorism targeting Chinese diplomatic missions or civilians," she said.

Algerian-based offshoot Al-Qaeda in the Islamic Maghreb has threatened to target Chinese interests, according to international consultancy Stirling Assynt.

Hundreds of thousands of Chinese work in the Middle East and North Africa, including 50,000 in Algeria, estimated the group, which has offices in London and Hong Kong providing risk advice to corporate and official clients.

China has accused Kadeer or masterminding recent violence in Xinjiang and said she is backed by "terrorists."

Kadeer denies the charges and US lawmakers have introduced a resolution demanding that China stop its "slander" of the 62-year-old former businesswoman and mother of 11, who spent six years in a Chinese prison.
